West Ham's Matt Jarvis: Cup win shows we are still fighting for Sam Allardyce

Matt Jarvis believes West Ham’s victory proves the players are all still fighting for manager Sam Allardyce and can pull clear of relegation trouble.

West Ham came from behind to score twice in the last 10 minutes through Jarvis and Madibo Maiga to set up a semi-final with Manchester City next month.

Allardyce has been under increasing pressure, with the club just one point above the relegation zone ahead of matches against Manchester United and Arsenal, but Jarvis believes last night’s win at White Hart Lane has given everyone renewed belief.

He said: “It was a hard-fought victory and a massive confidence boost for ourselves. It doesn’t get any better for us, getting a win away from home against a big rival and playing as well as we did.

“I don’t think it has ever been in doubt [that the players are behind Allardyce]. We work extremely hard and show great team spirit. We back the manager and it came out last night.

“Obviously, we just want to keep putting in the performances which we’ve been doing but getting the right result, which we’ve done here.

“We’ve created loads of chances but have just not been putting them away. We’ve kept eight clean sheets but we need to score when we get the opportunities.

“Can we get a result at Manchester United [on Saturday]? I don’t see why not. Teams have gone to Old Trafford this season and got results.

“They’re still a fantastic side but we can go there full of confidence after this result.

“At home against Arsenal, we’ll try and be as solid as we usually are and try to get some points.”

With United facing Chelsea’s conquerors, Sunderland, in the other semi-final, there is expectation that it will be an all-Manchester final at Wembley on March 2.

But Jarvis insists West Ham have what it takes to spring a surprise result against Manchester City. “It’s a massive challenge but I think people didn’t expect us to beat Tottenham either,” added the winger.

“We need to concentrate on the Premier League for the time being. This result is a massive confidence booster. We needed a win and to get it at Spurs is a massive thing.”
